Step-by-step explanation:
Given
s(t) = 10t²
To find s(2) and s(5) substitute t = 2 and t = 5 into f(t)
(a)
s(2) = 10 × 2² = 10 × 4 = 40
s(5) = 10 × 5² = 10 × 25 = 250
(b)
s(5) - s(2) = 250 - 40 = 210
This represents the distance travelled in 3 hours
(c)
The average rate of change is measured as
=
=
= 70 miles per hour

We have,
1 mile = 5280 feet
32 miles = 5280 * 32
= 168960 feet
1 hour = (60 * 60) = 3600 seconds
Now,
Converting 32 miles per hour to feet per second.
because 32 miles is 168960 feet and 1 hour is 3600 seconds
So, the answer is 46.93 feet per second
1 mile = 5280 feet
32 miles = 5280 * 32
= 168960 feet
1 hour = (60 * 60) = 3600 seconds
Now,
Converting 32 miles per hour to feet per second.
So, the answer is 46.93 feet per second
